Explanation: Could this close-by asteroid ever hit the Earth? Eventually yes -- but probably not for a very long time, even though the asteroid is expected to pass inside the orbit of the Moon next century. However, to better understand the nature and orbit of all near-Earth asteroids, NASA sent the robotic Origins, Spectral Interpretation, Resource Identification,

A Lecture I attended a last year! Found the video by the Geological Society of London!
Copied Video's Description:
Why Earth developed into the crucible of life, and Venus into a hostile wasteland

The present-day differences in the expression and intensity of volcanism on the planets of the inner solar system serves a testament to the

The universe is the biggest and oldest thing we know. It contains all existing matter and space. And its origin marks the beginning of time as far as we understand it. We don’t know what made the formation of the universe possible, nor why it occurred. The visible universe is currently about 93

Explanation: An unusual type of solar eclipse occurred in 2012. Usually, it is the Earth's Moon that eclipses the Sun. That year, most unusually, the planet Venus took a turn. Like a solar

Finding alien life on a distant planet would be amazing news - or would it? If we are not the only

Dark Molecular Cloud Barnard 68
Image Credit: FORS Team, 8.2-meter VLT Antu, ESOExplanation: Where did all the stars go? What used to be considered a hole in the sky is now known to astronomers as a dark molecular cloud. Here, a high concentration of dust and molecular gas absorb practically all the visible light emitted from background stars. The eerily dark surroundings help

Eclipsosaurus Rex
Image Credit & Copyright: Fred Espenak (MrEclipse.com)Explanation: We live in an era where total solar eclipses are possible because at times the apparent size of the Moon can just cover the disk of the Sun. But the Moon is slowly moving away from planet Earth. Its distance is measured to increase about 1.5 inches (3.8 centimeters) per year due to tidal

Global Aurora at Mars
Image Credit: MAVEN, LASP, University of Colorado, NASAExplanation: A strong solar event last month triggered intense global aurora at Mars. Before (left) and during (right) the solar storm, these projections show the sudden increase in ultraviolet emission from martian aurora, more than 25 times brighter than auroral emission previously detected by the orbiting MAVEN spacecraft. With a

This beautiful Hubble image reveals a young super star cluster known as Westerlund 1, only 15,000 light-years away in our Milky Way neighborhood, yet home to one of the largest stars ever discovered.
Stars are classified according to their spectral type, surface temperature, and luminosity.
